The Submerged Spire of Sarpedon the Shaper lies to the west of the Isle of the Dismemberer. On the northwestern shore of this island, crumbling steps spill from the shore directly into the sea. There, a seaweed choked stone path can be glimpsed winding down into the depths. At low tide, a quarter mile along the path, a lone onion dome may be seen poking through the waves. In the twilight of the sorcerer lords, The Submerged Spire was the jewel of the Shattered Isles. Within his submarine redoubt, Sarpedon penetrated ever deeper into the organic mysteries. Now, its for- lorn dome the roost of seagulls, its secrets slumber beneath the waves.
